Protect and insulate your wiring projects with this Heat Shrink Tubing. Designed with a 2.5:1 shrink ratio and medium wall thickness, this tubing bridges the gap between thin and heavy-wall alternatives, making it perfect for light-duty electrical and mechanical applications. Its dual-layer construction combines high-grade polyolefin with a heat-activated adhesive sealant, ensuring a moisture-tight seal that withstands temperatures up to 230°F (110°C) and remains flexible even at –67°F (–55°C). Trusted by auto technicians and electricians alike, this electrical shrink tube provides superior corrosion, fluid, and fungus resistance while meeting MIL-1-23053/4 specifications. An essential tool, it delivers unmatched durability and protection with every application.
